Hi, if the center mounted light works this is most likely going to be two bad brake light bulbs.
i changed the bulbs
Are you sure that you changed the correct bulbs?
did you check fuse 14 in the cargo compartment?
If there is no power to fuse 14 when the brake pedal is depressed I'd say you have a fault in the rear electronics module.
Have you tried swapping the relays?

I'd swap the brake light relay and the brake light shunt with similar ones in the relay box.
